Do I have to fill my tires with nitrogen since the dealer had nitrogen in it?

Don't waste your money messing with the nitrogen.

Unless you plan on racing it and are concerned aboiut reducing your pressure change by 2 psi, then don't worry about it. Use regular air. It's free and it won't make a darned bit of difference unless you're racing it. And by racing I mean road course racing with extended time where you're running flat-out and really working the tires in the turns.

I seriously doubt you drive "nascar" style on a daily basis to warrant using nitrogen in your tires....besides....it's really 
anyways. Don't fall into the "ohhh I've got Nitrogen in my tires" crowd.

Although regular air is fine, the nitrogen is unquestionable more stable with regard to tire pressure. It also does not seep out as easily. The benefits of being nitrogen filled diminish as you over time replace with air. But free is a pretty good price for air.

I've always wondered: If you use helium in the tires, will the car be lighter?

It's just another "gimick" used to sell cars or tires! Kind of like the $500 scothgaurd protection dealers used to put on your seat. It was a $10 can of scothgaurd spay! It's a big bag of

In my current C6 the dealer filled them for me and the psi was 30, a few months later and the psi is now 28.
Seems to leak as bad as regular old air.

Regular air is fine, but nitrogen is nice if you want a more stable air pressure in your tires. Not all that necessary for street driving. Nitrogen doesn't seep out as fast as oxygenated air and isn't affected by temperature as much either. Regular air = about - 1 lb./month for seepage and approx. +/- 1 lb. per 10* of temperature change. Full nitorgen will better that by at least 50%. That's not
If that were true and the oxygen seeped out first, after a few refills you would have nearly pure nitrogen. The only difference between air and pure nitrogen is that air normally has water vapor in it. Dry air works the same in all respects as dry nitrogen.

out of curiosity, i went to look at the new 370z at a local nissan dealer..
car had the 'blue' caps on the valve stems and a 300$ charge added to the sticker for this most precious of gases...
a relative bought a car bout 3 years ago. had the blue valves. he goes to get his oil changed and one of the local chains.. ask them to check/fill his tires (which needed btw) and they said.. no way we cant touch them blue valves!
scam scam scam..
i think it started in aircraft tires, cause of the heat when they hit the runway landing, nitrogen wont expand so much, less potential to pop a tire landing, racers picked up up looking for the tenth of a second difference (and i suppose it does make a difference here) finally the dealers picked it up to replace scotchguard, pin-stripping and undercoating..
